What am I supposed to do with Shamen?

[tinkthank]

Thanks!

- Moonvine bracelets give +nature, not +astral

- I cant forge any +astral items with a shaman, however, so that means I need to cast Coatl (expensive, and also level 7 conjuration! ouch, definately not early-mid game for me), or put some astral on my pretender.

I'm a huge fan of starshine skullcaps; I also love astral nations (my favorite is Tien Chi, not really an "astral nation", but as S&A I get astral 2 before too long).
Banner of the Northern Star is of course great -- but I'll be damned if I can get a shaman to make one.
